The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present application, it is further noted that, unless expressly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

In the field of electroplating, each type of electroplating may involve a plurality of processes that require processing of the surface of a component, and among these processes, processes that use chemical solutions may be involved. For example, in electroplating tin, the following plating line flow is typically included: chemical degreasing, water washing, high-pressure water washing, deoxidation, pre-soaking, an electroplating bath, a neutralization tank, hot water washing, pure water washing, blow-drying, blanking, steel strip deplating, spray water washing, tap water washing and hot blow-drying, wherein the 11 procedures relate to a conductive device (a device for providing charges for an element to be processed so as to enable the element to be processed to be electrified) and comprise the following procedures: a pre-soaking tank, an electroplating tank and a steel strip deplating tank; generally, the plating line uses 5 plating baths for a total of 20 cathode assemblies; the pre-dipping comprises 1 anode device, the steel strip deplating comprises 9 anode devices, wherein the electrolytic tin plating adopts cathode electroplating, the conductive device in the electroplating bath is also called as a cathode conductive device, and the anode devices are all anode effects and are also called as anode conductive devices.

In the current conductive device of the electroplating line in the industry, a positive electrode lead 30, a negative electrode lead 31, a positive electrode terminal 31, a negative electrode terminal 31, a fixing frame and a copper sheet 34 are fixed by titanium screws; and the fixed lower end is pulled together through a spring 33, so that the whole device is coordinated and assembled into the conductive device. Referring to fig. 1, a conveying structure 20, such as a steel belt, is disposed in the solution tank 10, and the steel belt is driven by a driving structure to move along the direction of the solution tank 10. The terminal 31 for connecting the power source is connected to a fixed bracket, and then divided into two terminal ends 32 by the fixed bracket, and the two terminal ends 32 are respectively connected to a copper sheet 34 fixed on another copper sheet fixed bracket (not shown in the figure), wherein the two terminal ends 32 are respectively located at both sides of the steel strip, and a spring 33 is connected between the two terminal ends 32, so that the two terminal ends 32 are close to each other by the tension of the spring 33, thereby making the copper sheet 34 contact with the steel strip in the solution tank 10. Since the steel belt needs to be moved to move the member to be processed on the plating line, friction between the steel belt and the copper sheet 34 occurs to cause abrasion of the copper sheet 34.

In order to ensure the effect of the conductive means, the equipment is frequently maintained during the electroplating process. In maintenance, the screws for mounting the copper sheets 34 and the like are often removed, and since there are many screws involved in each conductive device, the maintenance operation is very time-consuming, for example, in a tin-electroplating line, it takes 20 minutes to replace every 1 conductive device on average, and then it takes 10 hours to replace the conductive device of the whole electroplating line, and the 10-hour capacity is: 4m/min 5 pieces 60min 10 pieces 1200 pieces, 717.6 pieces are counted, and market QFN (Quad Flat No-lead package) is 4 pieces per piece, which is converted into rmb: 2870.4 ten thousand. The titanium screw and the titanium gasket are fixed on the groove wall by twisting a 6 mm tool. When the accessory is maintained every day, due to friction between metal and corrosion of plating solution acidizing fluid, the wearing and tearing of nut have been accelerated, lead to when the maintenance next time, the accessory is because of the wearing and tearing of nut lead to the accessory to become invalid to lead to serious waste. The market price of 1 titanium alloy screw is 35RMB, 19600 replacement is needed every year, and the counter is as follows: 69 ten thousand RMB. The market price of 1 copper sheet 34 is: 17RMB, 8000 changes are needed each year, and the counter is as follows: 13.6 million RMB.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a conductive device according to an embodiment of the present disclosure. The conductive device is applied to a solution tank 10 of electroplating equipment, and a transmission structure 20 which can move along the extending direction of the solution tank 10 is arranged in the solution tank 10. The device comprises two contact structures, namely a first contact structure and a second contact structure, wherein the first contact structure comprises a fixed end and a movable end, the fixed end and the movable end of the first contact structure can move relatively, the second contact structure comprises a fixed end and a movable end, and the fixed end and the movable end of the second contact structure can move relatively. When the conductive device is disposed in the solution tank 10, a fixed end of the first contact structure is connected to one sidewall of the solution tank 10, and a fixed end of the second contact structure is connected to the other sidewall of the solution tank 10; the movable end of the first contact structure can move in a direction away from or close to the transmission structure 20 relative to the transmission structure 20, and the movable end of the second contact structure can move in a direction away from or close to the transmission structure 20 relative to the transmission structure 20.

The device further comprises a fixing structure 50 and a terminal 31, the fixing structure 50 being used for connecting the first contact structure and the second contact structure, and the terminal 31 being used for connecting a power source. The terminal 31 is disposed on any one of the first contact structure, the second contact structure or the fixing structure 50, when the first contact structure and the second contact structure are relatively and fixedly connected through the fixing structure 50, the first contact structure is electrically connected with the transmission structure 20, the second contact structure is electrically connected with the transmission structure 20, and the power supply forms an electrical path to the element to be processed through the terminal 31 and the contact structures.

Wherein a portion of the first contact structure, the second contact structure or the fixing structure 50 may be made of a conductor. For example, when the terminal 31 is disposed on the first contact structure, which is at least partially a conductor, the power source forms an electrical path with the component to be processed through the terminal 31, the first contact structure, and the transmission structure 20; when the terminal 31 is arranged on the second contact structure, the second contact structure is at least partially a conductor, and the power supply forms an electric path with the element to be processed through the terminal 31, the second contact structure and the transmission structure 20; when the terminal 31 is disposed on the fixed structure 50, at least a portion of the fixed structure 50 and the first contact structure are conductors, and at this time, the power source forms an electrical path with the component to be processed through the terminal 31, the fixed structure 50, the first contact structure, and the transmission structure 20, or portions of the fixed structure 50 and the second contact structure are conductors, and at this time, the power source forms an electrical path with the component to be processed through the terminal 31, the fixed structure 50, the second contact structure, and the transmission structure 20, or at least a portion of the fixed structure 50, the first contact structure, and the second contact structure are all provided with conductors, and at this time, the power source forms an electrical path with the component to be processed through the terminal 31, the fixed structure 50, the first contact structure, and the transmission structure 20, and the power source passes through the terminal 31, The fixing structure 50, the second contact structure, the transmission structure 20 form an electrical path with the component to be processed.

In this embodiment, when the first contact structure and the second contact structure are disposed in the solution tank 10, the first contact structure and the second contact structure are respectively disposed at two sides of the transmission structure 20, when the component to be processed on the transmission structure 20 needs to be charged, the movable end of the first contact structure and the movable end of the second contact structure can be brought close to the transmission structure 20 by adjusting the movable ends of the first contact structure and the second contact structure, and then the first contact structure and the second contact structure are connected by the fixing structure 50, so that both the first contact structure and the second contact structure are electrically contacted with the transmission structure 20. Since the terminal 31 for connecting the power source is disposed on any one of the fixing structure 50, the first contact structure and the second contact structure, an electrical path can be formed between the terminal 31 and the to-be-processed member placed on the transfer structure 20, that is, the to-be-processed member may be charged (either positively or negatively).

The transport structure 20 may be a steel belt which is driven by a driving structure to move in the solution tanks 10, so as to drive the element to be processed to move from one solution tank 10 to another solution tank 10 on the plating line, and the element to be processed can be hung on the transport structure 20.

In this embodiment, since the first contact structure and the second contact structure each include a movable end that can be close to the transmission structure 20, when the first contact structure and the second contact structure are required to be in contact with the transmission structure 20, only the fixed structure 50 is required to connect the first contact structure and the second contact structure together, and when the first contact structure and the second contact structure are required to be separated from the transmission structure 20, only the fixed structure 50 is required to be separated from the first contact structure and the second contact structure, and then the movable end of the first contact structure or the movable end of the second contact structure is adjusted to make the first contact structure and the second contact structure far away from the transmission structure 20. Therefore, when the conductive device is maintained, screws do not need to be detached or installed, so that the speed of maintaining the conductive device is greatly improved, and the production efficiency can be improved. In addition, because the screws installed in the conductive device are fewer, the screws do not need to be disassembled and assembled in the maintenance process, and therefore the abrasion of the screws can be reduced, and the whole production cost is reduced.
